Extended
A hybrid CLOB from an ex-Revolut team, live on Starknet — sub-10ms off-chain matching with on-chain settlement, EVM-friendly deposits, up to 100x leverage.
A hybrid CLOB from an ex-Revolut team, live on Starknet — sub-10ms off-chain matching with on-chain settlement, EVM-friendly deposits, up to 100x leverage.
Extended is a perpetuals DEX built by a team with Revolut fintech backgrounds, running a hybrid CLOB: matching, risk management, and sequencing happen off-chain for sub-10ms performance, while validation and settlement happen on-chain via Starknet, inheriting Ethereum’s security through Starknet’s zk-rollup proofs. It migrated from StarkEx to Starknet in August 2025 and is built with an EVM-friendly design — deposit and withdraw from an EVM chain without a separate Starknet setup.
Extended is used for leveraged perpetuals trading across both crypto majors and TradFi-style instruments (EUR, S&P 500, gold, Brent crude) trading 24/7, with up to 100x leverage. The off-chain matching layer is built specifically to avoid MEV and frontrunning drag that fully on-chain order books can be more exposed to.
Reported fees run around 0.025% taker / 0% maker, with daily maker rebates up to roughly 2 basis points based on 30-day maker-share thresholds. No deposit or withdrawal fees on Extended’s own side, though bridging from an EVM chain may carry its own separate bridge fee — factor that in when comparing all-in cost to a platform native to the chain you’re funding from.
Extended has built a genuine reputation specifically around its hybrid CLOB performance and its Starknet migration, positioning itself as a “hyper-performant perp DEX.” It’s a comparatively newer platform relative to multi-year-established venues, and the recent infrastructure migration means less time running on its current Starknet-based architecture specifically than its overall project history might suggest.
Extended’s Season 1 Points Program has run since April 2025, distributing points weekly for trading volume, Community Vault deposits, and referrals (affiliate rewards unlock after $10,000 of personal volume) — and as of our research, no X10 token has launched, though Extended has publicly framed the points program as the qualification mechanism for a future distribution. Extended’s own terms state points create no entitlement to any specific allocation and can be adjusted at any time — worth reading literally, not just as boilerplate. See our pre-TGE farming roundup for how this compares to other open windows, and our airdrop farming guide for the general risk picture before committing meaningful trading volume purely to farm.
Beyond standard perps leverage risk, Extended’s off-chain matching/sequencing layer is a distinct trust surface from a fully on-chain order book, and the relatively recent StarkEx-to-Starknet migration means the current architecture has a shorter independent track record than the project’s overall history suggests. Evaluate the current Starknet-based deployment specifically, not just Extended’s brand recognition from its earlier StarkEx period.
This review is based on Extended’s public documentation, its migration announcement, and independent coverage of its architecture and fee structure. We haven’t run an original audit of Extended’s contracts on either its former StarkEx or current Starknet deployment — verify current fees, audit status, and market availability directly on the platform before trading.
Frequently asked
No — Extended's EVM-friendly design lets EVM users deposit and withdraw without a separate Starknet setup, despite settling on Starknet under the hood. That's a deliberate UX choice to remove the usual friction of a less mainstream L2.
The move (completed August 2025) shifted Extended from StarkEx's more specialized rollup infrastructure to Starknet's general-purpose zk-rollup — trading some of StarkEx's narrower optimization for Starknet's broader ecosystem and ongoing development. Verify current architecture details directly, since this kind of infrastructure migration can carry its own transition risk.
TradFi-style perpetuals trade 24/7 alongside crypto pairs, including instruments tracking EUR, the S&P 500, gold (XAU), and Brent crude — a broader market set than a crypto-only perps DEX.
